The 'machine co1np`ris`es,` "n general, a frame l t"Whio`h is r'rotatably attaeh'ed a crank axle 2 carried vbysupporting Wheels 3, a pair oi armst' carrying4 beetjpulling .tools` a pair ofsteeringwheels G, a guidingple'T, andafeontrolling lever 8.

The iframe 1 may be 'madeo-i' any suit-able material and 'in aiiyrequired shape,pre fer ably being mede of steel and beingap'proximately rectangular in" shape. It supports .anoperators seat `10 which is attacfhed'in'the rear.

Thefcrank axle is'onn'e'ctedfto vthe frame by .bearings l11, the supportingivheels 3 being 4journaled on the ends ofithe axle.

' `Fixed to the crank aXle is a crank lklshonf'n in Figure v2 connected by `a link'lvwithihe Controlling lever 8 which Vispivoted to the ltrarne and which fcooperatesy With a toothed .sector ',14- along VWhiehl it be adjusted. Movements oft the controlling Enlever are transmitted in this manner to tlierank aigle which .swings relative to the frame to vraiseand lower the"vvheels thereby 'effecting a lowering and raising movement-jot ythe framejrelativeto the ground. Spring-S connected betvveen the Iframe and the .Qmi-k-aX1eff0f normally bis? the axle in] a clockwise" d irection, the vpurpose of this ar- V: rangement being-to counteraet the Weight of 'the operator and to ymake iteasily 'possible to rise'the machine with one hand by'meens of thelever 8. It Will be not-edg by referring to Figures 1 and`2; that vthe greatest' fo-reefis exerted by this spring When/the machine is 1n lowered position' as' 'shown `in` Figure y1y and that, asthe machine moves toivardthe positionl of Figure "2y the tension'of'the spring is relieved. The location- `of'the parts is such that the machine is balanced in all positions of the controllinglever 8. In order to compensate for'operators' oi- 'difen ent` Weight` the springs may be adjusted by means of the'nuts on the endsof lthe'l links connecting' theV springs to the Atraine.

The 'steering Wheels are Carried? by aides having 'vertical extensions 16 'each jour naled inbearings 17 on Ithe trarne. Fiied to the upper ends of the vertical `,eX-te1i` s-ions lla're crank arms 18 connected by links; l9`

to a steering lever 20 pivoted' to anexjtension .21 of the seat'supporting ban The 'steering lever 20 is locatedso that it 'Inay'jb easily manipulated "by the ieetof the operaf" tor. The manner in' Which this mechanism "is operated "Will be clear by referring toj Figure 4. 'The' arrangementissuehtlit vWhen the operator "desires to steer ltothe rig'hvtlie Vpresses on theright end ofl 'the lever and vice versa. c

Provision is made(y for automatibally cientering the steering *lever 20 thereby makin-g it easier for the operator to Control the'ifrn- Vplernentby insuring that the steering Wheels rWill always be straight aheadnnle'ssfpositively guided to the right orleft bythe'foperator. For this purpose there is' provided a `Y-shaped member 43 (see-Fig. 5) 'slidably `mounted in a bracket 44 on member '21. The two arms of Vlthe Y bear in Semi-Circular slots in the lever 2 0. The "1f-shapedliiifemn `ber is normally biased into Contact Wit-h the Vlever bymeans of a spring ifi'betwveenfthe neck of 'the Y! andithe rear end of bracket steering the rightorleft, thedle'tt or right the 'JY-shaped member will bel puslied, badk- Wardly and'slightly to'one side, therno'unt` ing ofthe member beingsueh as to Vper- 44'. Whenever the'flever'QO -is moved-'Ito Y pressed.v The spring is inadestrong enough so that, when pressure is relieved from"th'e lsteering lever, the leveryvill be automatically returned to its'o'rig'inal positienbythe torce of the spring which tends to normally maintain the parts in the position illustrated in Figure 5.

. It is desirable to have the pole move trecly when the machine is in its lowered operating position because, at that time, it is desirable t steer the machine by means of the steering wheel and notl by the pole. On the other hand, it is desirable to have the pole rigid when the machine is in transport position, at which time the pole must serve as a guiding means. The mechanism for connecting the pole to the machine is arranged so that the pole is automatically connected rigidly with the machine when it is raised to transport position and is likewise automatically released when the machine is lowered to operating position.

The )ole 7 is pivoted to a carrying member 22 iy means of a bracket Q?) which permits the pole to swivel in a horizontal plane and also in a vertical plane. ln other words, the pole is connected to the member 2Q by a universal joint. rlhe carrying member Q2 is pivoted at the point 24 to the trame and has attached to it a bar 25 connected by a pin and slot connection 26 to a crank 2T-on the crank axle.

Then the machine is in its working position as illustrated in Figure l, the rear end of the carrying member Q2 is lowered as illustrated, but, as the machine moves to its raised position illustrated in Figure 2. the rear end of this member is raised by reason i o' the fact that the crank 27 on crank axle 2 swings in the pin and slot connection with the member 25 and raises the carrying member asthe crank axle turns clockwise in raising the machine.

A chain 28 connects the rear end of the pole 7 with an arm 29 on the crank Q7. There is also loca-ted on the rear end et the pole a plate 30 having in it' al notch 3l with which cooperates av roller 32 on a bracket 238 mounted on the carrying member This connect-ion ot the pole to the machine operates as follows:

lVhen the machine is in lowered operating position, the chain Q8 is loose as ,illustrated in Figure l, the rear end ot' thc pole T is tree ot the carrying member 22. and the pole is free to move up and down and sidewise to a limited extent. the latter movement being limited by the length ot the chain 2S. but heing Sutlicient so that all ordinary movements ot the pole will not atleet the steering ot' the machine in any ay. the machine being steered at that time b v the steering wheels tl.

As the machine is raised. the crank 2i' on the crank axle rotates rearwardly, that is, clockwise, thereby lifting the rear end ot the carrying member 2Q, and also moving the chain 28 rearwardly so as to bring it to a taut position. The linal position of the parts is illustrated in Figure 2 in which the chain is taut and the roller 32 on the earrving member 2Q is engaged in the notch ill on the bracket 30 on the tongue. ln this position, the rear end ot the tongue is rigid with the carrying member Q2. lt cannot be swung' sidewise without steering the machine. lVhile the tongue connection has been moved to this position, the steering wheels` havil been raised clear of the ground. unordingly'7 when the machine is in its raised position, the steering wheels no longer serve as a steering means, but the tongue has been converted into a steeringmeans l'or guiding the machine which, under these conditions, is a two-wheel carriage.

The sloping surfaces ill; and li o' the bracket 3() and the fact that the chain 2S is tightened as the machine is raised. insure that the rear end of the tongue will be s\vun; r to a position such that the roller 32 seats in the notch 3l.

1When the machine is lowered. the revei';'e action takes place, that is. the chain QS is loosened and the roller 32 moves out ot the slot 31 leaving' the rear end ot the tongue. free to swing relative to the frame.

t should be noted that the connection ot' the pole to the machine including the meehanism for automatically locking it in position can be moved sidewise to permit the pole to be in different positions as required for two or three horses. The bracket lil can be connected in any one ot a pluri lit otholes 40 in plate 4l, the stub pole 22 can be slid along the pivot rod 2l. and the crank 27 can be adjusted to a different position on the crank axle.

The operation of the machine as a whohl is as follows:

lVhen the machine is being ined. it, is in the position shown in Figure l. ln this position, the trame is lowered and the :steering wheels G are in Contact. with the ground. rl`he tongue 7 is 'lree to move in both a horizontal and vertical plane and consequciith1 does not act' to steer the machine nor are movements ot the machine transterred to the pole. The operator `guides the machine hv means ot' the toot lever Qtl which steers ttn` Sil tltl

However. it this lifting movement be rontinued. or il ithe desired to rai-'e the inachine to transport position, the operator pulls on the lever 8 until it reaches the position shown in Figure 2. This movement swings the crank axles in a clockwise direction and raises the frame so that the beet; pulling arms as well as the steering wheels 6 and the coulters 61 are raised clear of the mamar ground. This *raisingi movement mayi fbe easilyy .aeeomplis'li'ed 'in View 'of theI-.iaet that the spring serves 'to' `balance" fthe ma'ehine torce-lis required to'fmove vthe lever Y 8 i During this *raising Voperation the pole 'Tis broi'ightliaek te itsreentral'I-position and loeked rigidly fte" ,thetrame of the mafeliine iso that 4Vit then ants asafg-u'iding f lne-fans. j'lhelsteering ivlieels Giare no'lon'ger `l L() o'1`3'er-ativel tor suoli purpose because th'eyiarfe outset Contact with thegfround.
